### BEGIN INIT INFO

# Should-Stop:       $remote_fs
# Default-Start:     2 3 5
# Default-Stop:      0 1 6
# Short-Description: start/stop the cntlm proxy
# Description:       ntlm is meant to be given your proxy address and becomming
#                    the primary proxy then, listening on a selected local port. 
#                    You point all your proxy-aware programs to it and don't ever
#                    have to deal with proxy authentication again.
### END INIT INFO
